Solution-based mixtures can be classified as true solutions, colloidal solutions, or suspensions depending on the particle size of the solute. Solid mixtures include alloys, which are homogeneous solid solutions of metals that are difficult to separate. An example given is brass, which is a homogeneous mixture of copper and zinc that takes on properties between the two metals.
IS MATTER AROUND US PURE- SEPARATION TECHNIQUES
This document discusses various separation techniques used to separate mixtures, including separating funnel, chromatography, centrifugation, simple distillation, and fractional distillation. A separating funnel uses differences in density to separate immiscible liquids. Chromatography separates components at different speeds through a mobile and stationary phase. Centrifugation uses centrifugal force to separate insoluble materials from liquids. Simple distillation separates mixtures based on differences in boiling points. Fractional distillation uses a fractionating column for repeated condensation to separate mixtures by boiling point.
Solutions, suspensions, and colloids
This document discusses solutions, colloids, and suspensions. It defines solutions as formed from a solvent and solute that contain small particles that do not separate or scatter light. There are three types of solutions: unsaturated, saturated, and supersaturated. Colloids have medium sized particles that cannot be filtered but can be separated by semipermeable membranes. Examples include fog, milk, and blood plasma. They scatter light, known as the Tyndall effect. Suspensions have very large particles that settle out and can be filtered, like particles of mud in water.
Solutions, suspensions, and colloids
A solution is a homogeneous mixture that forms when a solute dissolves in a solvent, such as salt dissolving in water, resulting in particles too small to filter. A suspension is a heterogeneous mixture where particles separate over time, like dirt in water, and can be filtered due to its larger particles. A colloid is between a solution and suspension, with particles that scatter light but do not separate or filter.

This document discusses the classification and properties of pure substances and mixtures. It defines pure substances as elements or compounds that consist of a single type of matter, while mixtures contain two or more pure substances mixed together. Mixtures are classified as either homogeneous, containing substances mixed uniformly, or heterogeneous, containing visible particles that can be separated. The document also discusses various techniques for separating components of mixtures like evaporation, centrifugation, distillation and crystallization.
Mixtures
A mixture is a combination of two or more substances that are not chemically combined. There are two main types of mixtures: homogeneous mixtures that look the same throughout and heterogeneous mixtures that look different throughout. Mixtures can be categorized into three types - solutions, colloids, and suspensions. A solution is a homogeneous mixture where particles cannot be seen, a colloid is a mixture with tiny particles suspended in between the sizes of a solution and suspension, and a suspension is a heterogeneous mixture where particles can be seen and separated through settling or filtration.
Online Solutions
This document provides information about solutions and solubility. It defines key terms like solute, solvent, saturated solution, and solubility. It explains that a solution is a homogeneous mixture of substances where one substance dissolves in another. Water is called the universal solvent because it can dissolve more substances than any other solvent. Not all substances are soluble and solubility depends on temperature, the nature of the solute and solvent, and other factors. The document also discusses different types of solutions and rates of dissolving.
Diet
An individual's diet consists of the foods and drinks they regularly consume. Dieting aims to achieve or maintain a certain weight through controlled eating. People's dietary choices can be influenced by ethical, religious, clinical, or weight control reasons, though some follow unhealthy diets out of habit rather than conscious choice. Common diet types include vegetarian, weight control, detox, and crash diets. The advantages of dieting are weight control, disease prevention, more energy, better mood, and longevity, but disadvantages can be hair loss, slower reaction time, low blood sugar, depression, and organ damage.

In this chapter we will study about characteristics of mixtures and its types, how they are different from pure substances, colloids, suspensions and solutions, separation techniques for components of mixtures and their commercial use, physical and chemical changes, metals, non metals and metalloids, elements and compounds.
Solution
This document discusses types of mixtures and solutions. It defines homogeneous and heterogeneous mixtures. Solutions are homogeneous mixtures of a solute dissolved in a solvent, forming a single phase. Factors that determine solubility, such as temperature and pressure, are described. The document outlines concentration units like molarity, molality, and percent composition. It also discusses solution processes and the energetics of dissolution. Key topics covered include saturation points, Henry's law, and separation techniques like ultrafiltration.
Solution-----(Pharmaceutics)
This document discusses different types of mixtures and solutions. It defines homogeneous and heterogeneous mixtures, and describes true solutions, suspensions, and colloids. It also defines key terms related to solutions such as solute, solvent, saturated, unsaturated and supersaturated solutions. Finally, it discusses various ways of expressing the concentration of solutions, including molarity, molality, mass percent, parts per million/billion and more. It provides examples and equations to calculate concentrations using these different units.
Solutions
A solution is formed when a solute dissolves completely and uniformly throughout a solvent. There are three main types of solutions: gaseous solutions where gases are dissolved in other gases; liquid solutions where solids, liquids or gases are dissolved in liquids; and solid solutions where solids are dissolved in other solids. The solubility of a solution depends on the temperature - as temperature increases, more solute can typically dissolve.
Unit 2
1. The document discusses aqueous solutions and their properties. It defines solvation as the process where solvent particles surround solute particles to form a solution.
2. For ionic compounds, solvation occurs through hydration where water molecules surround the ions. For covalent compounds, solvation involves the formation of hydrogen bonds between the solute and water molecules.
3. Factors that affect the rate of solvation include agitation, surface area, and temperature. Increasing agitation and surface area as well as raising or lowering the temperature can increase or decrease the rate of solvation.

A solution is a homogeneous mixture of two or more substances, where the solute is dispersed uniformly throughout the solvent. The solubility of a solute is dependent on temperature, pressure, and the nature of the solute and solvent. Solubility is expressed as the maximum grams of solute that will dissolve per 100 grams of solvent. Colligative properties, such as boiling point elevation and freezing point depression, depend only on the number of solute particles and not their identity.

This document discusses solutions and related concepts. It begins by defining matter and the different states of matter. It then discusses solutions in depth, including the components of solutions, different types of solutions, factors that affect solubility rates, and ways to express concentration. Examples are provided throughout to illustrate these concepts. Concentration is discussed further, including percentage by weight and by volume. Factors that affect how quickly solutes dissolve are also outlined.
Properties of solutions
- A solution is a homogeneous mixture of two or more substances. The component present in smaller amounts is the solute, while the component present in larger amounts is the solvent.
- Factors like temperature, pressure, and whether substances are polar/nonpolar affect solubility. Generally, solubility increases with temperature but decreases for gases.
- A saturated solution contains the maximum amount of solute dissolvable under a given set of conditions, while an unsaturated solution contains less. A supersaturated solution contains more solute than normally possible.

This document provides information about solutions, colloids, and suspensions. It defines each term and gives examples. A solution is a homogeneous mixture of substances with particle sizes smaller than 1 nm that does not scatter light. A colloid has particle sizes between 2-1000 nm and can be seen, distinguishing from solutions by scattering light. A suspension is a heterogeneous mixture with particle sizes over 1000 nm that can be seen and separated by filtration.
General Chemistry 2 Q1L4 Solutions properties.pptx
A solution is a homogeneous mixture of two or more substances. The substance present in the smaller amount is called the solute, while the substance present in the larger amount is the solvent. For a solution to form, the solute particles must disperse uniformly throughout the solvent. The solute and solvent interact through intermolecular forces, with the solute particles becoming solvated by the solvent molecules. Solubility is dependent on various factors including temperature, pressure, and the nature of the solute and solvent.
Is matter around us pure
- A mixture contains two or more pure substances that are mixed but not chemically combined. Mixtures can be homogeneous, with a uniform composition throughout, or heterogeneous, with a non-uniform composition.
- Common types of mixtures include solutions, suspensions, and colloidal solutions. Solutions are homogeneous mixtures where one substance dissolves in another. Suspensions are heterogeneous mixtures where one substance is suspended throughout another but does not dissolve. Colloidal solutions are heterogeneous but appear homogeneous, with one substance dispersed throughout another in small, suspended particles.
- The components of a mixture can often be separated using differences in their properties, such as differences in boiling points, densities, or whether they are miscible with each other

Properties of Solutions
This document discusses key properties and concepts related to solutions. It defines a solution as being made up of a solvent and one or more solutes. The solvent is the substance that exists in the greatest quantity, while solutes are all other substances present. Solutions can be solid, liquid or gas depending on the state of the solvent. The document also discusses concentration, solubility, factors that affect solubility like temperature and pressure, and how to increase the rate at which a solute dissolves.
Solutions
A solution is a homogeneous mixture composed of a solute dissolved in a solvent. A solution is formed through solvation, where solvent particles surround solute particles and pull them away from each other. The solubility of a substance depends on factors like temperature, pressure, and the properties of the solute and solvent. Increasing temperature, pressure, surface area, or agitation can increase solubility and the rate of solvation. Concentration refers to the ratio of solute to solvent and affects properties like reaction rates.
Q1C2L1 Types of Solutions general chemistry 2.pptx
This document discusses different types of mixtures including homogeneous and heterogeneous mixtures. Homogeneous mixtures are solutions that are evenly distributed while heterogeneous mixtures are not evenly distributed. Heterogeneous mixtures include suspensions, where particles settle out, and colloids, where particles are dispersed but do not settle out. Solutions are homogeneous mixtures of a solute dissolved in a solvent where the components are evenly mixed on an atomic scale.
Mixtures
A mixture forms when two or more substances are combined such that each substance retains its own chemical identity. Everywhere around us are made up of mixtures. We can see them in nature, along the surface of the earth, in the oceans and in the foods we eat. There are infinite numbers of mixtures that can be combined into homogeneous or heterogeneous.

The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Is Matter around us PURE
- 1. IS MATTER AROUND US PURE?????
- 2. According to a scientist something is pure, it means that all the constituent particles of that substance are the same in their chemical nature. A pure substance consists of a single type of particles.
- 4. MIXTURE Mixtures are constituted by more than one kind of pure form of matter, known as a substance. Soft drink and soil are not single substances .Whatever the source of a substance may be, it will always have the same characteristic properties. Therefore, we can say that a mixture contains more than one substance.
- 5. SOLUTIONS A solution is a homogeneous mixture of two or more substances . ex: Lemonade soda water we think of a solution as a liquid that contains either a solid, liquid or a gas dissolved in it. But, we can also have solid solutions (alloys) and gaseous solutions (air).
- 6. solution Solvent Component present In larger amount Ex: water Solute Component present In lesser amount Ex: sugar
- 7. PROPERTIES OF SOLUTIONS • A solution is a homogeneous mixture. • The particles of a solution are smaller than 1 nm (10-9 meter ) in diameter. So, they cannot be seen by naked eyes. • The solute particles cannot be separated from the mixture by the process of filtration.
- 8. At any particular temperature a solution that has dissolved as much solute as it is capable of dissolving, is said to be a saturated solution If the amount of solute contained in a solution is less than the saturation level, it is called an unsaturated solution.
- 9. SUSPENSION A suspension is a heterogeneous mixture in which the solute particles do not dissolve but remain suspended throughout the bulk of the medium.
- 11. COLLOIDAL SOLUTION IT IS A HETEROGENOUS MIXTURE OF TWO OR MORE COMPONENTS HAVING PARTICULAR SIZE LESS THAN THAT OF SUSPENSION AND GREATER THAN THAT OF SOLUTION
- 12. TYNDALL EFFECT COLLOIDAL PARTICLE CAN SCATTER A BEAM OF VISIBLE LIGHT BECAUSE OF ITS SMALLER SIZE. THIS PHENOMENON IS KNOWN AS TYNDALL EFFECT
- 14. SEPARATION OF MIXTURE OF TWO IMMISCIBLE LIQUIDS
- 15. SEPERATION USING SUBLIMATION (MIXTURE OF NH4Cl AND SALT)
- 16. CRYSTALLISATION WHEN A SATURATED HOT SOLUTION ALLOW TO COOL WE CAN OBSERVE THE FORMATION OF SOLID. THIS IS KNOWN AS CRYSTALLISATION.
